teruakohatu··on Bricklink suspends Marketplace operations in 35 countries
> The secondary market hurts their sales for new sets, or so they believe.

I think the secondary market drives sales. People need to believe that the overpriced sets they are purchasing, never open, and stash in the attic will make them a fortune on the secondary market one day.

That is an interesting piece of internet history, thank you for sharing.

Can you tell me about "Simtel"? I have never used a BBS but from looking at that ISO it was a collection of software downloaded from BBS' ?

> Stick a microphone and camera outside on a robot and you can get unlimited data of perfect quality (because it by definition is the real world, not synthetic).

Be careful with mistaking data for information.

You are getting a digital (maybe lossy compressed) samples of photons and sound waves. It is not unlimited, a camera pointed at a building at night is going to have very little new information from second to second. A microphone outside is going to have very little new information second to second unless something audible is happening close by.

You can max out your storage capacity by adding twenty ML high megapixel cameras recording frames as tiff file but gain little new useful information for every camera you add.

I never said they were lying. They haven’t stated that they do not tweak compute, and we know the app is updated regularly.

> 1. The nerf is psychologial, not actual. 2. The nerf is real but in a way that is perceptual to humans, but not benchmarks.

They could publish weekly benchmarks. To disprove. They almost certainly have internal benchmarking.

The shift is certainly real. It might not be model performance but contextual changes or token performance (tasks take longer even if the model stays the same).

teruakohatu··on The new Aider-CE fork of Aider is now official
Aider has some weird anti-features like an explicit inability to handle git submodules.

Now I dislike submodules, but I can’t get a massive codebase refactored just because of my tooling preferences.

teruakohatu··on Blasting Yeast with UV Light
In New Zealand our cow’s milk is separated into its components and then reconstituted and bottled. I would think it’s the same elsewhere too.

> The challenge is the institutional knowledge that never made it into code or documentation and has walked out the door.

This is a problem a compiler cannot fix, and is a very real problem.

teruakohatu··on Developers are choosing older AI models
I agree, much slower and worse output. It is substantially worse now than it was weeks ago.

It spends a lot of time coming up with “UI options” (Select 1, 2 or 3 with a TUI interface) for me to consider when it could just ask me what I want, not come up with a 5 layer flow chart of possibilities.

Overall I think it is just Anthropic tweaking things to reduce costs.

I am paying for a Max subscription but I am going to reevaluate other options.

teruakohatu··on GHC now runs in the browser
Pandoc is an extremely popular Haskell tool.
teruakohatu··on New analog chip capable of outperforming top-end GPUs by as much as 1000x
Faster than an H100 for solving 128x128 matrices. But it’s not clear to me how they tested this, code is only available on request.

> We have described a high-precision and scalable analogue matrix equation solver. The solver involves low-precision matrix operations, which are suited well to RRAM-based computing. The matrix operations were implemented with a foundry-developed 40-nm 1T1R RRAM array with 3-bit resolution. Bit-slicing was used to guarantee the high preci- sion. Scalability was addressed through the BlockAMC algorithm, which was experimentally demonstrated. A 16 × 16 matrix inversion problem was solved with the BlockAMC algorithm with 24-bit fixed-point preci- sion. The analogue solver was also applied to the detection process in massive MIMO systems and showed identical BER performance within only three iterative cycles compared with digital counterparts for 128 × 8 systems with 256-QAM modulation.

teruakohatu··on Nearly 90% of Windows Games Now Run on Linux
Thanks for the advice. I spend 99.99% of my time in a terminal, a browser and vscode.

The graphical environment is neither here nor there for me, I just want to do an update and cuda libraries/nvidia drivers not break and for my OS to boot!

teruakohatu··on Uv is the best thing to happen to the Python ecosystem in a decade
A vanilla python can write files, edit ~/.zsh to create an sudo alias that executes code next time you invoke sudo and type in your password.

uv installing deps is hardly more risky.

teruakohatu··on Nearly 90% of Windows Games Now Run on Linux
I must be the one Data Scientist in the world whose PopOS has twice failed to boot after updates. To the point I have give up on it.

My stack is so vanilla (nvidia, python, R) I can’t think what the issue is. Maybe hardware.

teruakohatu··on Testing out BLE beacons with BeaconDB
I think they meant triple how often they broadcast, not using a radio frequency x3 higher on the spectrum.
teruakohatu··on Show HN: Create-LLM – Train your own LLM in 60 seconds
Hacker News is a better place when we don’t attack people sharing their work. Your point was made.

Well done to the author for shipping code. I look forward to trying it out.

teruakohatu··on California invests in battery energy storage, leaving rolling blackouts behind
I struggle to understand why journalists consistently failed to use Wh as a unit of power. People generally can understand it because it is how they are billed and how appliances are rated.

Even on HN people will defend not using Wh because there is some grid or city in the USA that bills differently.

From the README:

> Preview can only open a small subset of the files I have.

> Visual: U.S. map overlaying DG store density and proposed Gold Site distribution.

Nothing says LLM “generate me a white paper” more than text description of visuals that do not exist.

teruakohatu··on A Global Mining Dataset
The author writes a significant amount about their workstation, and how cleaning up the geometry can be helpful when accessing it remotely over S3.

The dataset is a 8,000 row spreadsheet.

My advice when working with such a small dataset is not to overthink it.

teruakohatu··on Synology reverses policy banning third-party HDDs
The Synology DS925+ for example does not have GPU encoding. For an expensive prosumer-positioned NAS this is crazy. They can't let us have both 2.5gb NICs and a GPU.
teruakohatu··on Microsoft 365 Copilot's commercial failure
> just added GPT 5 to Copilot so it’s much better than it used to be

Only marginally in general office use. Maybe is has better coding capabilities, but there is no way its the same sized model used on ChatGPT or via. OpenAI API.

teruakohatu··on Walmart U.S. moves to eliminate synthetic dyes across all private brand foods
Wikipedia says about carmine …

> To prepare carmine, the powdered insect bodies are boiled in ammonia or a sodium carbonate solution, the insoluble matter is removed by filtering, and alum is added to the clear salt solution of carminic acid to precipitate the red aluminium salt. Purity of color is ensured by the absence of iron. Stannous chloride, citric acid, borax, or gelatin may be added to regulate the formation of the precipitate. For shades of purple, lime is added to the alum.

At this point how natural is it?

> many of the OpenRouter providers were degraded on benchmarks compared to base models, implying they are serving up quantized models to save costs,

Do you have information on this? This seems like brand destroying for both OpenRouter and the model providers.

teruakohatu··on The elusive roots of rosin potatoes (2022)
That is interesting and confirms my suspicions that there is rosin and there is unsafe rosin.

While I think New Zealand made rosin would come from pine wood not pulp, no commercial producer is going to tell me if the product uses any toxic chemicals if they get the slightest hint I plan on cooking with it.

teruakohatu··on The elusive roots of rosin potatoes (2022)
I nearly re-submitted that a few weeks ago.

It’s an American delicacy I would love to try, but here in New Zealand I can’t find a local manufacturer of pine rosin that will sell to consumers, and no idea if modern processing of rosin is more risky than it was back when it was on Cracker Barrel menus.

teruakohatu··on Is a movie prop the ultimate laptop bag?
> This was in nice suburb in New Zealand, so it was a bit of a surprise.

A friend had her ancient Toyota’s back window smashed in and they stole an old dirty blanket lying on the back seat that they could have gotten for free from any number of places (clean and in better condition)

In a warm climate New Zealand suburb.

My takeaway at the time was that a subset of thieves will steal anything, with zero rational basis and no regard for consequences.

A paper bag would be just as enticing.
